It's different.
Disco is usually held in a popular ballroom. Disco was the most popular time in 1980s and 1990s because of its dynamic rhythm, strong coordination, catchy style and simple and popular dance difficulty.
DJ, as a kind of rubbing music in large discos, attaches importance to percussion and post-processing of electronic sounds brought by heavy bass, and is the most commonly used music for young people to release pressure and dance at will.
Disco is easy to remember because of its simple catchy theme, but the disadvantage is that the melodies complement each other. Once the theme song is changed, it is not original enough and difficult to copy. Therefore, some classic discos lose their original flavor after being renovated into DJ, and the rhythm is only the most classic.
What impressed me the most was the theme of real-life quick play in the classic movie "Magic Palace Empire". This year's newly released Magic Palace Empire: Destruction changed the original disco music to DJ, which just met the landlord's question, because everyone could hear the obvious differences and characteristics between the two kinds of music.
